Ok there is a weird but frustrating bug. It is the 2nd time it has occured and i cant get rid of it (its in all my games multi and single). Pressing the 'esc' button does not remove what was previously selected. For example at the start of the game i will make a probe, then select my group of probes to mine. Now if i press the 'esc' key the group of probes are still selected. There is nothing i can do to 'deselect' this group outside of leftclicking on the nexus. If i do this now the nexus is selected and i canoot remove this selection without left clicking on something else. Now i gone looking for a 'sticky' feature in options that may have turned on but i cannot find it. Please help as i am so used to doing this it is really throwing me off and i cannot play multi player without it.
do u hav any solution yet? i experience the same problem too for more than 5 times. everytime this problem occurs, i loss a match. at first, i thought it was the problem of my mouse, but still i face the same problem after changing with the other mouse.
I had this issue in StarCraft 1... Left mouse button was getting stuck. I had to replace the mouse. If you have a laptop and use a desktop/portable mouse like I do, check and make sure your touch pad buttons aren't stuck.
