Hi @guy038, your summary is right. By hard disks I meant the classic ones with spinning platters. SSDs get 4 threads, like your key. MultiReplace asks Windows whether a drive has a seek penalty, which only drives with moving read heads report. Those get 1 thread, CD/DVD drives too, and to be safe also USB disks that don’t answer that question. And thanks for checking the hit counts, good to see all three engines agree.

@xomx Thank you for quick reply. I think it is a rare case, for I know many Windows 11 PCs with NP++ installed where this issue isn’t present. The machine having the issue is a laptop: HP ZBook, Betriebsystemname Microsoft Windows 11 Pro Version 10.0.26200 Build 26200 Systemhersteller HP Systemmodell HP ZBook Power G7 Mobile Workstation Systemtyp x64-basierter PC System-SKU 1J3X8EA#ABD Prozessor Intel® Core™ i7-10750H CPU @ 2.60GHz, 2592 MHz, 6 Kern(e), 12 logische® Prozessor(en) BIOS-Version/-Datum HP T75 Ver. 01.25.00, 08.06.2026 SMBIOS-Version 3.2 Version des eingebetteten Controllers 52.49 BIOS-Modus UEFI BaseBoard-Hersteller HP BaseBoard-Produkt 87EC BaseBoard-Version KBC Version 34.31.00 Plattformrolle Mobil Secure Boot On PCR7-Konfiguration Erweiterung zum Anzeigen erforderlich Windows-Verzeichnis C:\WINDOWS Systemverzeichnis C:\WINDOWS\system32 Startgerät \Device\HarddiskVolume1 Gebietsschema Deutschland Hardwareabstraktionsebene Version = “10.0.26100.1” Name Intel® UHD Graphics PNP-Gerätekennung PCI\VEN_8086&DEV_9BC4&SUBSYS_87EC103C&REV_05\3&11583659&2&10 Adaptertyp Intel® UHD Graphics Family, Intel Corporation-kompatibel Adapterbeschreibung Intel® UHD Graphics Adapter-RAM 1,00 GB (1.073.741.824 Bytes) Installierte Treiber C:\WINDOWS\System32\DriverStore\FileRepository\iigd_dch.inf_amd64_7bee8b32df4bfc59\igdumdim64.dll,C:\WINDOWS\System32\DriverStore\FileRepository\iigd_dch.inf_amd64_7bee8b32df4bfc59\igd10iumd64.dll,C:\WINDOWS\System32\DriverStore\FileRepository\iigd_dch.inf_amd64_7bee8b32df4bfc59\igd10iumd64.dll,C:\WINDOWS\System32\DriverStore\FileRepository\iigd_dch.inf_amd64_7bee8b32df4bfc59\igd12umd64.dll Treiberversion 31.0.101.2140 INF-Datei oem191.inf (Abschnitt iCML_w10_DS) Farbebenen Nicht verfügbar Farbtabelleneinträge 4294967296 Auflösung 3840 x 2160 x 60 Hz Bits/Pixel 32 Speicheradresse 0x00000000E7000000-0x00000000E7FFFFFF Speicheradresse 0x00000000C0000000-0x00000000CFFFFFFF E/A-Port 0x00004000-0x0000403F IRQ-Kanal IRQ 4294967277 Treiber C:\WINDOWS\SYSTEM32\DRIVERSTORE\FILEREPOSITORY\IIGD_DCH.INF_AMD64_7BEE8B32DF4BFC59\IGDKMD64.SYS (31.0.101.2140, 42,20 MB (44.254.136 Bytes), 18.06.2026 22:09) Name NVIDIA Quadro P620 PNP-Gerätekennung PCI\VEN_10DE&DEV_1CBD&SUBSYS_87F0103C&REV_A1\4&22A337FB&0&0008 Adaptertyp Quadro P620, NVIDIA-kompatibel Adapterbeschreibung NVIDIA Quadro P620 Adapter-RAM (1.048.576) Bytes Installierte Treiber C:\WINDOWS\System32\DriverStore\FileRepository\nvbl.inf_amd64_2fde6b246e89db94\nvldumdx.dll,C:\WINDOWS\System32\DriverStore\FileRepository\nvbl.inf_amd64_2fde6b246e89db94\nvldumdx.dll,C:\WINDOWS\System32\DriverStore\FileRepository\nvbl.inf_amd64_2fde6b246e89db94\nvldumdx.dll,C:\WINDOWS\System32\DriverStore\FileRepository\nvbl.inf_amd64_2fde6b246e89db94\nvldumdx.dll Treiberversion 32.0.15.8242 INF-Datei oem303.inf (Abschnitt Section060) Farbebenen Nicht verfügbar Farbtabelleneinträge Nicht verfügbar Auflösung Nicht verfügbar Bits/Pixel Nicht verfügbar Speicheradresse 0x00000000E8000000-0x00000000E8FFFFFF Speicheradresse 0x00000000A0000000-0x00000000B1FFFFFF Speicheradresse 0x00000000B0000000-0x00000000B1FFFFFF IRQ-Kanal IRQ 4294967276 Treiber C:\WINDOWS\SYSTEM32\DRIVERSTORE\FILEREPOSITORY\NVBL.INF_AMD64_2FDE6B246E89DB94\NVLDDMKM.SYS (32.0.15.8242, 105,49 MB (110.618.856 Bytes), 02.06.2026 21:35) So pretty standard configuration, except for 4K resolution, i think. Maybe we can find some similarities between the affected devices?

Hello, @coises, I confirm that, if I choose the GDI (most compatible) rendering mode instead of the DirectWrite (default), the spliting action seems to always occur after 78 letters P ! I verified this assumption with, both, the proportional Times New Roman font and the fixed width Consolas font BR guy038

@donho Is it possible to add a button (for the search bar) to clear the text field?
