I'm making an app which has some more sophisticated searching and filtering options. On the main screen, any changes I make now can render the editor unresponsive for minutes, many times I run out of patience and refresh the page.
I'm using SQL Server data sources, lookups for localization amongst other things.
The problem started when I tried writing filter formulas for the gallery on the main screen. Any changes in the formula could completely freeze up the editor, leaving me no choice but to edit the formula in an external text editor. Even then, when pasting the new formula, it could freeze.
I tried tweaking every app setting I could find, nothing makes a difference as of yet. The only experimental feature I'm using is the group control, which is essential. Could this be causing the problem?
