With "standard calling conventions", do you mean I have to write
code like with Delphi (push/pop ebx,edi,esi)? Yesterday, I spent all
day long to remove all these push/pop :-)
Should I also write push/pop for eax,ecx,edx when REGCALL is not
defined?

I will do that.

Unfortunately, I am not able to reproduce it myself! Now that I use
a lot of units, it almost no more occurs. In fact, today it occurred
only once not when using the mouse but when hitting Ctrl-F9.
