Hi again,

ok, Jim Pendleton from ITTVIS found the solution... it is an old bug in
dialog_pickfile (CR 14734). Basically, it triggers an event with some delay.

The workaround from Jim is attached, in case anyone else has the same
problem!

Thanks to Jim and all of you that had a look at this!

Jean
