That sounds like a resource problem. I think one of our applications has a resource leak. Open the task manager and add the columns for handles and gdi objects. Check if the numbers in these columns grow for one application.

I used Working Time Tracker. It is very flexible in reports and exports. I used the export to a csv file, than loaded the csv file into excel and from there using a Macro and "SendKeys" i moved the data to Navision, which was the company time tracker. :-)

Unfortunatly, the development seems to be dead.
