Apex Version: 4.1.1.00.23
Theme: Cloudy 24 (With customisations to the wrapper around the body section.)
Can't see it because it's asking for a Google password. Please illustrate problems with examples on apex.oracle.com, then we can investigate it directly in APEX.
I have replicated this on oracle.apex.com (Initially I did not do this as the version is different, but I can still replicate the issue).
If you go to this page in the app (I have turned off authentication).
Then go to Actions > Select Columns, the buttons are blue.
Browser Mode: IE9
Document Mode: IE9 Standards.
Many of our users are still using IE9.
I know that the application views better in Chrome or Firefox, and never recommend IE, but this is their SOE so was wondering if there is a CSS patch to get this do display nicely?
