Crash removing genre from tree [#7673]

[timelezz]

I have this problem already for a long period in MM4. I send a trillion report by the auto-message system. But apparently it is not taken up. So I report it here, I guess. When I remove a genre from the genre tree, I get this error

Is MM aware of this already?

[Peke]

Nope, I see this first time.

Does same thing happen when:
- MM is started as skinless ("MediaMonkey (non-Skinned).exe")?
- While there is no Playback?
- Run MM as Administrator?

[timelezz]

I ran some tests. I am Administrator and entered in Skinless mode.

When I remove a genre from the tree, without the playback on, No problem!
When I remove a genre from the tree, with the playback on. PROBLEMO!

Code: Select all

Access violation at address 00508E6A in module 'MediaMonkey (non-skinned).exe'. Read of address 00300031.

Once I had this error, it doesn't matter anymore if playback is on or not. the error keeps coming whenever I remove a genre from the tree.

This should be fixed in the latest build, can you confirm?

[timelezz]

Yes, I tested it right after downloading the new version. And it was solved indeed. Great fix, thanks!
