>I believe I fixed or make it work without problem, but I still reproduce the error once in the development enviroment but XP did not give me the detail of the error so I shut down the VFP run. I save the form as a class and create 10 identical form. So everytime I call the combobox dropdown method did not call the same form again, when they reach the number 10 go back to 0 and start the process again. So far I dont get the C5 error in the Exe version. Doing the same process where I got the problem. Look like the form get corrupted when you called so many times without giving some time to finally release. So creating 10 clones of the same windows sound like fix the problem with garbage. Also I put some garbage collector function in the same form. But so far is working fine.

Great. So, it was a corrupted form? Glad you fixed it.
