I'm been having the same problem in Designer for a while now. Frustrating!!
I found a temporary workaround. Example:
I have the Move Tool [V] selected and I press the spacebar to quickly use the View Tool [H] and release the spacebar. Like others here, after releasing the spacebar the "View Tool" hand still shows and it's stuck even though the "Move Tool" is still selected in the tool bar. To quickly get back to the View Tool, I press the "H" key on keyboard and then press the "V" key.
I have to do this everytime I use the View Tool spacebar shortcut.
