Do not apply selected theme from within the preferences dialog, as th…
…at crashes sporadically. Instead, rely on the info dialog telling the user he should restart the app. Related to #465, and probably solves it.

This could already be solved by my recent commit, see above. But that only leaves the current theme active for the session after changing it in preferences, so the theme gets switched on the next restart. I'm not sure if you got that crash within the same session after changing the theme, did you?

I could reproduce the issue: (still on

Steps to reproduce

  1. (Material Theme is selected)
  2. Open settings
  3. Choose Carbon Theme
  4. Apply
  5. Choose Windows 10 theme
  6. Apply
  7. Choose Windows 10 dark theme
  8. Apply
  9. Choose Material Theme back
  10. Apply
  11. Click OK to close
  12. Error "Access violation at address 00000000007C75E8 in module 'heidisql.exe'. Read of address 0000000000000010"

But if I click Continue application, it works.


So it's probably not a very common/blocking issue...

Build 5442 does not have my fix from above. Please update to the latest build. In that newer build, the "Apply" button does not change the theme at once. Instead, it just shows a message saying the user should restart HeidiSQL to apply changed settings.

I guess this is now solved, so I'll close this issue.
