Timeless Time & Expense Enterprise Web installed on Windows XP Professional may encounter problems due to the default limit of 10 connections to IIS. This limit may appear as random occurrences of missing images or the web application not responding to actions on the task hierarchy, calendar or entry list.
The connection limit can be raised as high as 40 to reduce or eliminate these problems. There are many articles with instructions on how to increase the limit. If this does not eliminate the problems, you will need to move to one of the other options.
