Will be back with more info when I get time to check everything.
Trying to run things in between other more priorized activities, but will be back.
Resourse issue seems not the case since in that case it would concern other programs as wel and not happen when computer is not doing anything else.
For the rest I will come back when I get time to check.
Seems misteriously solved.
No idea what the reason was and (un)fortunately no longer reproducable. Have not touched the specific computer other than for reading docs and the normal problems as iI always do.
Puzzled but glad now. Problem is. I can't reproduce it anymore.
Good thing of course, but I will not risc getting the issue again after reinstallng perl. That I would do if I were admin.
Tnx for the help. Hope this issue will not return.
