1. ctrl + F to search, then replicate the search window's settings. IMPORTANT: you need to chose "Preset" first and then "color". The editor doesn't output that properly.
2. Use search button until you find a "create dialog label" action.
3. Press replace.
4. Iterate step 2 and 3 until you fixed all labels occuring in your triggers.
I noticed that all of my buttons now default the text color to the same color of the button, ignoring the style color of the text. It made my dialogs go from looking pretty nice to terrible, is this problem related?
Maybe this is a bad workaround, but I just replaced all of my single-line Create Label actions with the more generic Create Dialog Item (label) and then Move, Size, and Style with separate lines of code. Increases code footprint but fixed my color issues.
Now in WoL 2.0.4 I'm running into labels truncating my text after a paragraph or so and adding "...", which cuts off lots of text. Not the case in HotS Beta.
