Attached patch makes it look better. Remaining issue that text area should be erased regardless, even with empty text. That's probably why erasing code was unusually merged with WM_PAINT originally. This needs more work. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.
