Thanks for the advice, I might try that later. However, I have 
noticed that my DLL does not cause any errors nor does it crash 
the app when switching between my DLL and other third party 
plugins. There is only one other plugin that crashes the app 
after my dll was active (otherwise there's no crash). I've tried 
several solutions now but to no avail. I don't think it's the 
other plugin's fault, as it works usually fine, but maybe there 
is a conflict somewhere in the dark realms of memory.
