File menu > Preferences crashes program

[greatzot]

Description
When trying to open Preferences from file menu, the program crashed. Tried without any tablature files open and got the same result.

To Reproduce
Go to file menu and try to open preferences.

Version
Windows 10, power tab alpha 19.

Does MIDI playback of a tab work for you? The main non-trivial thing the preferences dialog does is finding all the MIDI devices / ports that are available

Also, is there any crash log when this happens, or is it a hard crash?

Just tried playback on a score and it worked. I'm not sure about a crash log--where would that be if there is one?

[cameronwhite]

Generally there should be a dialog that pops up with details about the crash, but if not the log should instead be printed to the console if you're launching from a terminal

I'm just launching from the Windows start menu (well, the Open Shell version of it I use), and there is no dialogue pop-up, it just shows the typical "program/computer is doing something" icon for a bit and then closes. But just to make things more interesting, I went upstairs and tried on my desktop computer, also running Win10, and in that case I could open the preferences dialogue. The laptop does have more software overall installed on it than the desktop, so maybe there's some conflict with some other program, but not sure how to track it down if so, other than just guessing and closing stuff.

Hmm thanks. I'd try looking at the audio / MIDI device settings in the control panel and maybe try disabling some MIDI device(s) to see if that avoids the crash?

The main non-trivial thing the preferences dialog does is search for MIDI devices and query their port names etc, so maybe a bad device driver or something like that could crash
