Hi guys, im fairly new to using inksacpe and do struggle to find it user freindly, for the last few times of using the software every time I want to select a different tool I have to click at the bottom of the screen, in fact everytime i want to do a next click i have to click at the bottom of the screen in between (uder the colour charts). Also when trying to select a font i have to click and hold the font arrow and then whilst holding the mouse button move up and down to look at fonts. if i let go of the mouse buttom the font menu disappears back up into itself, this is very frustrating.
Yesterday however, i was using it as normal, editing some text when all of a sudden everything changed. i could change from text to select arrow without having to click at the bottom of the page, the font menu would stay open withouth having to hold the button down. It was brilliant, working as i had always suspected it should have work all the long. This morning however its back to normal

HELP!!!
Did i do something or is it just my computer?
Thanks
James
