Borderline unusable performance degradation

Do you set WM_SETREDRAW to false for the comboxes before filling it?

No I don't, but the user seems to have the problem even with a fresh wincmd.ini (no history items to be added).

Ok, but still this should be done (or at least be tested) for users with lots of history items.

On my PC (4th gen i5, 24 G RAM, SSD, Windows 10 22h2): Alt+F7 opens ~ 1 second on x32 and slightly faster on x64 (almost no matter, Alt+F7 or Alt+Shift+F7). F5 opens almost instantaneously (<0.5 s).

Some updates. Got a new laptop. I'm running the same version of windows, mostly the same set of software, same settings set up in seemingly the same usual way, everything TC does is instant. Like, less than 0.3 seconds delay on alt+f7. This hardware is higher specs, but it's definitely not 100x higher.

Memory integrity is disabled on both machines.

So maybe it was some third party software installed on the old machine which caused the slowdowns? The most probable candidates are Antivirus suites and "optimizers"...
