Mouseclick Bug

[jungletek]

Windows XP SP3, vlc 1.0.5.

Many UI elements don't respond to mouseclicks, especially but not limited to Save/OK/Cancel buttons at the bottom of config menus. Dropdowns and tabs seem to be affected also. Interestingly, the click seems to change the focus of the "highlight' one uses when using KB only to navigate, but won't (usually) activate the UI element (i.e. dropdown won't dropdown, save button won't click and save, etc.).

Possible that this was also in 1.0.4, but I'm not sure. It (almost) definitely was not in 1.0.3.

Let me know if you need any other info, as I'm desperate to sort this out... using keyboard only to navigate menus is VERY frustrating.

Thanks in advance.

Removal of %appdata%\vlc folder helps?

I just upgraded from an old version of VLC to 1.0.5 today and I'm having a similar problem, as clicking on the upper menu does work for me. At first install no clicks would work at all other then clicking on the menu options. If I tried to select a bullet or dropdown menu in the Preferences menu nothing would happen. I uninstalled, downloaded from another mirror and reinstalled. This time I could click things but it wouldn't always work, it could take several clicks or won't work at all. It acts this way for all menus that I can select.

While playing a movie I cannot click any of the features such as 'pause' or 'stop', nor click and hold the slider to move it back and forth to different times during the movie. Clicking on the bar to simply jump to another point in the movie also won't work.

I couldn't find the %appdata%\vlc folder that you speak of.

Also using Windows XP sp3.

Open Windows Explorer or start -> run and paste %appdata%\vlc there and press Enter.

I assume that uninstalling the previous version (using the installer) removes appdata? Or manually uninstalling through add/remove programs? Because I've done both of those...

Just tested it now, by renaming the appdata folder so a fresh one was created, and still having the same problems.
Interestingly, out of frustration, I rapidly clicked the left mouse button and the right mouse button in an alternating fashion... after a second or two of this, it would register a click and tick a checkbox, close the prefs menu, etc.

Perhaps it's some sort of timing issue where VLC is not polling for mouse events often enough? If I was a more proficient programmer, I'd take a look at the source myself and try to debug the issue. But I'm not, so I leave it to the experts

Installer doesn't remove %appdata%\vlc folder.

I tested for both possibilities.

You have some custom GUI skinning engine in use? Or Wacom tablets?

Yes to the wacom tablet. Is this a known bug? If so, I apologize for wasting your time.

[VLC_help]

Some people have complained certain problems with Wacom tablets. (we have no clue what is the problem, but it is prolly related to Wacom software)

[Faehl]

I use a wacom tablet's mouse as well. I had simply switched back to what the op said last worked, 1.0.3, and I haven't been having any problems at all.

Thanks for helping me find %appdata%\vlc, I've deleted that and when I try out 1.0.5 again I'll post on how it goes.

Only Wacom software I'm running is the drivers. As has been said, there were no problems in 1.0.3... so I hope the solution can be found eventually. Is there any way we can help you to debug the problem?

If you know how to use gdb, you could download VLC debug builds and check if there are something strange in mouse events. Or use Spy++ or similar tool and check out messages send to VLC.
