I tried the latest updated and the TParamListBox entry issues with spinner and edit fields is fixed (if you want me to nit pick a little the entry field cuts off just a tip of the first letter as it goes to widen the field, but it's not really a problem). However the line spacing issue moving from 250% to 100% still exists as shown in the picture from 17 days ago but it's not a critical issue. So TParamListBox is now usable for production release.
The main issue left (out side the potential RTL issue) is with the AdvTreecomboBox. It still too huge! I've attached pictures this time, one from the 100% screen and the other from the 250% screen (you'll see it is way out of whack).
This is the 100% screen (I put it on the bottom like the 250% screen which I had to do for it to even fit).
This is on the 250% screen - note the width and height are WAY too big (it should be the width of the combo box like on 100%).
The interesting thing is it looks like it's 2.5x too big which matches the 250% (it's like it sized to the correct size some place then sized a second time which made it 250% too big). I don't believe it was like that before fixing the enter/escape key issues, but I can be wrong.
