Selection in the IDE's code window

[CD <dessere.claude@xxxxxx>]

Hello, 

Since updating to Gambas=3.21.3 9c8e9a3 (master), 
the selection (of a word, a line, or the entire page using Ctrl+A) 
in the IDE's code window is transparent. 
Only the line numbers change color. 
 I've looked in the Tools/Preferences menu without success. 
 I checked the exported and re-imported theme file; there is indeed a selection
setting, 
but changing its value doesn't affect the code window. 
 What do I need to do to see the selection? 

 P.S.: In Find/Replace, the searched word is correctly selected!Regards
