BC HexViewer 2.3.1 / TaskSwitchXP Pro 2.0.11 hang

[chrisjj]

Devs, you might like to know of this undesirable interaction between Beyond Compare HexViewer 2.3.1 and TaskSwitchXP Pro 2.0.11.

With TaskSwitchXP Pro running, I
1 open two files in the Hex Viewer
2 edit one in an external program
3 ALT-TAB back to the Hex Viewer

The Hex Viewer UI hangs - any click on its window is ignored, except to sound a beep.

If I do this without TaskSwitch Pro, I see a 'File(s) changed on disk. Reload?' dialog box.

If at 3 I instead click on the app's title bar or task bar button, I don't get the hang, and I do get a 'File(s) changed on disk. Reload?' dialog box.

Further info: this happens with the File Viewer too.

I can get this to hang with the Hex Viewer, but not the file viewer. Are you using http://www.ntwind.com/software/taskswitchxp.html
?

I'm going to open a bug report for the Hex Viewer for now.

Trying more, I find that out of ten tests, I got the hang nine times, and the other time the dialog box appeared as expected.

Thanks. I've added your stats to the bug report. Let's see if the taskswitcher people have any ideas.

Further info:

1 TaskSwitchXP Pro support didn't succeed in reproducing this on their machine.

2 I tested on a second WinXP SP2 machine and got the same failure.



3 A method of recovery less costly than CTRL-ALT-DEL is:

1 Open Notepad
2 ALT-TAB to BC2 and back to Notepad
3 Close Notepad - BC2 appears correctly.

Chris,

We've reproduced this with the Hex Viewer, but not with the File Viewer. However, I noticed from your screen shot you're using BC 2.4. Try using our current release version 2.5.1, it might clear up the problem for the File Viewer.

Thanks.

I'm baffled as to how you can get the problem with one viewer and not the other.

Same problem:

Re: BC HexViewer 2.3.1 / TaskSwitchXP Pro 2.0.11 h

We set up another virtual machine, reinstalled the software, and were unable to reproduce it with 2.5.1 and their newest taskswitch. We can get it to happen with our hex viewer, which they are unable to test with due to plugins only working for a registered version.

If they would like, they can contact us at support@scootersoftware.com
and we can give them a temporary trial key to use in order to see this problem on their end.
