Hi,
recently in worksheet as I type sql statement text goes invisible.
For example I typed "select 1 from dual" run it and then want to change query. And suddenly text goes invisible like this
Only way I found to "refresh" worksheet is to hit select all Ctrl+A to force sql developer to display text again.
Not long ago I executed "Reset Windows to facotry settings" and I suspect that that caused this convenience.
