Using Visio 2k10 for a while, and there still is some very irritating Bugs, that been there forever (at-least since 2k, cant remember if they were there pre-MS though)
In shapesheet, when Adding, Deleting Rows, as well as changing Row-Type, Visio Either unfolds all section or folds them, very irritating that you need to find the section and row one are working on, especially if one have some 30+ Geometry sections.
Still in Shapesheet, on the formula entry row, underscores "_" are displayed as space " ", and Commas "," as dots "."
Cut and paste does not woerk very well, ctrl-X/C/V seems to work, but not Right-klick
The "Auto-Connect" feature (or bug as I see it) that connects shapes seemingly randomly, when dropped on a page, how on earth do I shut it of, cant find it.
