After clean config and import of options from b3 to RC1.
I noticed that the icons in Regex tool were really small, so I used tools->options to adjust.
#1: It takes a long time after changing the icons size and hitting apply before Slick is responsive again.
It is long enough that Windows complained that Slick was not responding and I almost killed it.
#2: The icons in Regex tool do not change size - even after restarting Slickedit.
#3: The icons in Options get bigger, but the small bitmaps are still displayed
See attachment showing Options and the icons in RegEx after changing the size and hitting Apply.
#4: After restarting Slickedit, open Tools->Options.
The nav icons in the top right are messed up - sometimes blank, sometimes just the up arrow - until you move or resize the Options window.
