during serial port acess panel ist locked!

[FischeFr]

could someone tell my why and how to change that?

LabVIEW doesn't lock the front panel while accessing serial ports, so we'll need a lot more information about your program to diagnose your problem. Describing what you're trying to do or posting a picture of your VI's diagram might help.

hmm, well..
what else could be a reason for a locked panel?

- events caught by event handlers

what else ?

a sub-VI was called by an event handler
