Admin level users (district level staff) have the ability to edit the six or nine week calendars.

Recently, some people have reported that when they try to enter dates, no matter what they enter, it is deleted as they type.

This is an issue specific to Internet Explorer 8. 

To correct the problem, follow these steps:

1) Start Internet Explorer
2) Click Tools (from the main IE menu)
3) Select Compatibility View Settings
4) Click the Add button to add sourceprosoftware.com to the list of websites (if any) that are viewed in compatibility mode.
5) Click Close to close the Compatibility View Settings screen
6) Close Internet Explorer

You may then go back into the CMTS Admin and you SHOULD be able to enter the new calendar dates.

If this doesn't fix the problem, please contact SourcePro Software at 888-461-8858 for assistance.
