At the end of that method, I put ThisForm.Enabled=.T. At this point, the method is finish, so the interface become available again and Visual FoxPro process everything in the buffer. So, ThisForm.Enabled was never used because it was during a process.

If for some reason it's impossible, I found that VFP used to be awaked during some process by things like WAIT Window "" Timeout 0.1
