I am really grateful for the new version! The new tools are really welcome. But I experience a tool hangup very often when I try to select pixels using the rectangular selection tool.
All I see is a small blue selection rectangle of 1x1px on the position I tried to drag a rectangle. But I cannot seem to do anything except for moving my cursor. I cannot erase pixels or draw them. And it really is starting to get rather frustrating. This bug did not exist in the previous version.
