Archer30 I tried to reproduced bug but did not have luck. I tried various scenarios to recreate bug using latest launcher 2.955 that includes R73 HD mode (a few week old).

I found this F12 wont work when
- HD help dialog is displayed (F1 on adventure map and in combat),
- Town dialogs (magic guild, dwelling upgrade, castle upgrade, leprechaun bank, Peons dialog...). But it work on army buy screen and all other "classic info" dialogs...,
- Hero henchmen screen...,
- "Welcome to gem settings" dialog.

F12 trigger ReloadErm method in all cases, but its exit from method when ErmTriggerDepth is no 0. In all above cases it is not 0.
Seems to me that all dialogs that related to HD mode has ErmTriggerDepth>0.

If you have additional info how to reproduce bug i can take look further...

Bug report:
Also, during gorilla testing i found that game crash when you try to reload scripts (F12) in hero meeting screen when quest log is opened. Crash occurs later, when quest dialog close button is hit.
Steps:
- Meet hero,
- Open quest dialog (any hero),
- F12 - sound is plays as sign of succeed reload,
- Close quest dialog,
- HD mode crash.
Can someone confirm this bug too?
