Dialog prompts shown on wrong screen

[support]

In our source code, we do not have the possibility to specify a target monitor for any message.
During our test with our monitors, all requester messages are logically displayed over the window which has the focus.

In any case, in order to have a chance to find a workaround of this problem, which seems to be an OS / video driver problem, we need to be able to reproduce it. So we presently are not able to help for this problem.
