I'm using a Ribbon Bar and have some F keys set to launch some items. The tools that are buttons work as expected (they will launch the function). I'm having a problem with a textbox tool. If the ribbon is on the tab that the tool is on, it works as expected (sets focus to the tool). If the ribbon is on a different tab it will change to the tab containing the tool, and then gets the exception "Can't activate a tool that is not visible." and does not set focus to the tool. Any ideas?
This issue was fixed on 4/1/10 (issue TFS30074) in versions 9.1 and later.
Just in case someone searches and finds this...I put this in as support request. There was a bug and it is being fixed in 9.2 and 10.1
