None that I know of. I use DmQueryRecord allot without any consequences. I
would start looking at any strings used by form C and make sure they are not
stomping on other variables.
You could also remove any processing done in your FrmInitForm and see if it
returns.
There is also a possibility you are running out of heap space. You can use
MemHeapFreeBytes to compare the available heap before, during and after your
routines are called.
Your description of your code is a little vague, if you are still having
problems you may want to consider posting snippets of your code.
