WeBuilder 2018 v15.4.0.206 freeze with Dark Theme + PHP CHM.
Steps:
1. Apply interface style "Flat Dark"
2. Options -> Preferences -> PHP Setting -> PHP Documentation set "Use PHP documentation in HTML or CHM format" and select CHM file from drive. I'm try use a "php_enhanced_ru.chm"
3. Create new PHP file (or open) and call the help of any PHP function
4. In CHM help goto tab "Search", input any function for search and click "Enter"
PHP Manual in CHM freeze and does not respond to requests (only Taskkill).
This issue does not reproduce on "Flat Blue", "Flat Grey" or "Classic Flat"
