Working in FileMaker 10 Advanced in Windows Vista environment. (Vista certainly not my choice).
I have two files, MAIN & CONTACTS, each with a handful of tables. The match field for these files is generally a unique, 8-digit all numerical, student ID.
PROBLEM: Just lately (everything has worked fo years)....> When I open the CONTACTS file it appears on the screen for about 1.5 seconds then disappears! It does not matter if I have the MAIN already open or not. The window is not being automatically minimized into the task bar. [my first guess] If I choose Windows > Show File from the menu, the opening screen again shows for about 1.5 seconds and disappears!
ANYONE have a clue to what is going on?????
