I may well be going completely nuts - but seem to have lost the ability to have Firefox open as well as say Thunderbird and go back and forth clicking the icon on the task bar when either open. Now have to minimize them to find the task bar. And the add on bar on Firefox now where the task bar was. Hope that makes sense. Using versions 17 on Firefox Thunderbird. Checked with IE 8 same so must be my computer settings not the programs - I did it - hands up - guilty. Started with update from MS I think suddenly got the open icons grouped on the right hand side of task bar with all on fast start showing and had to go up or down button to get back to them so moved the division back to the left and went back to first 3 fast start and click to get rest as usual. So what did I do wrong? Anyone know?
