Can't edit ticket

[zip]

Hello

when a tickets comes in via customer.pl interface, i can work on it and everything is working fine.
when a tickets comes in via email and i manually click on fetch email i can work on it and everything is working fine.
but when a tickets comes in via email and the ticket is fetched automatically (every 5 min) i can't do any changes on the ticket. if i click on lock or if i change the service the page reloads but nothing happens.if i look in the database i see the changes affect but on the web interface nothing changes.

maybe something with the cron/scheduler is wrong?

What does the system log say about things?
Do you have any PostMaster Filters or Generic Agents that are causing issues?
What have you changed from stock?

1) to set the prority

- i installed the otrs by the source file, no installer. this was my guide: http://wiki.otterhub.org/index.php?titl ... _and_IIS_7 + installation of otrs scheduler
i had some trouble to install the conw, maybe there i a problem with the user rights, i will check it

permissons should be ok, dont know what could cause this strange behavior

if i reinstall cronw and the scheduler, everything works fine when the first ticket comes in. After that the strange behaviour begins. Anyone can help me with this problem? If not i have to reinstall otrs today.
