When a program window is opened or compiled, there is a flash of white across the entire window. This is most noticeable when setting a background color (via Fonts>Editor>Bkg) and it does not happen in SQL Windows or other window types.

It would be very nice if Program Windows acted like SQL Windows in this regard.

Please see the attached video for an example. Unfortunately the recording does not include the menu, but in it I performed the following steps:
1) Open a Program Window x2 - notice the flash
2) Execute the Program Window x2 - notice the flash
3) Open a SQL Window x2 - no flash
4) Execute the SQL Window x2 - no flash

We'll check it out.

This has been fixed in 15.0.1. Thank you so much! It felt obscure and trivial when I reported it, but thank you for taking it seriously and making the program just that little bit better.
