If you’re old like me, you may find the new windowing as confusing as I did.
I just got an Android Tablet recently otherwise I would NEVER have figured this out. If you have a dialogue box with no ‘X’, just click yer mouse anywhere -outside- the window. Don’t bother hitting ‘Esc’. There is no escape.
Apparently, that acts as a ‘cancel’. It’s the ‘Android touch’ way of doing things.
I’m just stunned that one can’t assume that ‘Esc’ means cancel anymore. (Sorry, anger leaked out. )
