I haven't tired it with a GUI app. but I did have problems this weekend 
when trying to use the MySQL unit. It would constantly crash on me when 
trying to close the connection not when opening as you experienced. I 
discovered that when I use the example code but insure that the 
variables that it wants to use are global but not local to the procedure 
it would work OK. However, while it does now work I do see one output 
value that is corrupted which is a time value which doesn't effect 
things. This time value only gets corrupted when I run the procedure 
with the MySQL code.

So just to assure you, yes it appears at least from my perspective that 
something is amiss in the MySQL unit.
