Here’s a work-around for the tabbed button issue (the text of the hilited tab is white on a white background, thus unreadable)
on preOpenCard if the platform is "MacOS" and BigSur() is true then repeat with x=1 to the number of btns of this stack if the menuMode of btn x of this stack is "tabbed" then set the backgroundColor of btn x of this stack to black end if end repeat else repeat with x=1 to the number of btns of this stack if the menuMode of btn x of this stack is "tabbed" then set the backgroundColor of btn x of this stack to empty end if end repeat end if pass preOpenCard end preOpenCard function BigSur --LC 9.6.1 reports "Big Sur" as version as 10.16, though Apple is calling it 11 - this covers both set the itemDelimiter to "." put the systemVersion into tVersion if item 1 of tVersion>10 or item 2 of tVersion>15 then return true else return false end BigSur Just put this in your main stack and Bob’s your uncle. Speaking of Bob, he has a customer control that circumvents the issue too. I’ll let him chime in to let you know where you can find that, —Marty _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
