When we open a folder(d:\test1\test2\test3) directly by the full file path instead of first d:\ then d:\test1 then d:\test1\test2,the the key {BROWSERBACK} can't work.However,the key backspace can turn it to the parent folder(d:\test1\test2)#12290; I make a action for {BACKSPACE},but it doesn't work in this situation..I try it in other place,it works well.And the key in the keyboard works well too.
I click Start>Run and entered "C:\Program Files\Microsoft Games" and hit Enter. The Explorer window opens and the action [which is acSendKeys("{BACKSPACE}")] takes me to the parent folder.
