Descriptive Problem Summary:
When you reach the end of the row of tabs in Dream Maker, using ctrl+tab, it skips back to the first one, and you can no longer use ctrl+tab, nor ctrl+shift+tab until you click onto another tab.
ctrl+shift+tab always works fine and never gets stuck.

Numbered Steps to Reproduce Problem:
1. open multiple 'windows' tab things.
2. ctrl+tab between them
3. get to the last tab and ctrl+tab again
4. goes back to the first one, like it should
5. can no longer ctrl+tab

Expected Results:
continue to switch between tabs normally, like in ctrl+shift+tab, just not backwards.

Actual Results:
ctrl+tab gets stuck when it loops back to the firts tab.

Does the problem occur:
Every time? Or how often? Always.
In other user accounts? Yes.
On other computers? Other people confirmed, yes.

Ctrl+shift+tab (tabbing in reverse)

Did the problem NOT occur in any earlier versions? If so, what was the last version that worked? 496.1138 is the only version with this issue, obviously.

Workarounds:
ctrl+shift+tab instead.
