seems that this is not the native FileMaker login box - could it be that there is a trigger that fires by content-change?
thanks for reply markus
No!! its a file maker native box.to login to my application those should have an account in my file and my file having onwindowsopen script trigger.as you know its not possible to attach script triggers to filemaker native box.
why use on windowOpen instead of onFirstWindowOpen ?
If you're running FMP Advanced, you can start FMPA, then activate ScriptDebugger before open your solution.
You will then see if any unwanted Script get's triggered.
