Take any column (for example column "WhereClause" in AD_Tab) and set the column reference to 'Text'.
Open window contains field links to this column (for example window "Window, Tab & Filed").
The field "Sql WHERE" is displayed now with little triangle locate at bottom right corner (pic. 1).
Click on the triangle and pull it to the right => text contained in field creeped under the gray panel and did not be displayed (pic. 2)
This is very specific to google chrome - other browsers don't have that feature.
Cannot reproduce it with actual version
