Again I stumbled across something....
Apparently, when the path (folder oder filename) contains one of the "umlaute" (üÜ, öÖ or äÄ) watching the TeX-file fails. Even though compiling using the usual + R works fine. Systemwide encoding is (supposed to be) UTF8.
Is that meant to be that way? - and - is there a simple way to fix or work around that? (Besides not using these letters in the path... ;)
thanx in advance and kind regards,
Patric
