Key event lost just after (~100ms) focusing Total Commander

[derji]

Key event lost just after focusing Total Commander.

Steps to reproduce:

1. Open Total Commander (11.00 64-bit (2023-08-02)) and navigate to a directory with several items. Make the first item active.
2. Open another program (for example Chrome).
3. Focus on another program (make that other program window active).
4. Alt-tab to Total Commander and within 100ms press the "down arrow" key.
5. The active file doesn't change.
6. Press "down arrow" key again - now it works as expected.

The issue happens also when you click on the TC's title bar to focus it (instead of alt-tab).
It is not specific to the "down arrow" key - other keys (F3, F7, Tab, ...) also have no effect when presses within ~100ms after focusing the Total Commander window.

I've just downgraded to 10.52 (2022-10-26) and it works fine.

OS: Microsoft Windows 10 Pro / 10.0.19045 N/A Build 19045

I can reproduce this with both TC 10.52 and TC 11.00 if I almost press Alt+Tab and Arrow-Down at the same time. It is not every time it happens though.

Since I can also reproduce it with TC 10.52 - I cannot be certain that it is a TC bug. I can actually reproduce it with Windows Explorer too...

Thanks petermad for trying to reproduce the issue!

I've created the following AHK script and calibrated the last "Sleep" on TC 10.52. Then re-installed TC 11.00... and it works fine (with the script and manually).

I will let you know if the issue reappears. Thanks!

Code: Select all

#SingleInstance Force
^Q::
	; Make sure TC window is active and there is at lease one another program opened
	; Press Ctrl+Q to run the test
	Send {Home}
	Sleep 250
	Send !{Tab}
	Sleep 1000
	Send !{Tab}
	; For 10.52 Win64 (2022-10-26) the shortest delay (22) after
	; which the 2nd item in the current directory is selected
	Sleep 22
	Send {Down}

Are you able to reproduce it with Explorer too like petermad?

No. I only had this issue with TC 11.00 before re-installing it.

Total Commander ignores navigation in the file panels while it is re-reading them. Each time you switch from a different program to Total Commander, it re-reads the two panels, but refreshes the list only when there are any differences.

You can reproduce this easily by going to a directory with a lot of files.

This behaviour is intentional.
