I've added some menu actions to toggle various text view attributes named in the subject. The default for Simulator and my devices is to have these features turned on. But I'm finding that toggling them in my menu actions doesn't actually work. Toggling spellchecking or smart quotes (I haven't yet bothered to add more actions and test them) to .off does indeed set the correct value on the UITextView, but the features are still happening when I type (soft or hard keyboards behave the same). What's wrong? Is it simply broken and is caching the initial value or something? 18.4 is being used on my Simulator and my devices. I also tried 18.3.1 in Simulator with the same results.

Not quite but maybe sorta related to the errOSAInternalTableOverflow problem I asked about in a different thread, this one deals with crashes our app gets (and much more frequently lately after recent OS updates (15.7.3) are OK'd by our IT department). Our app can run multiple jobs concurrently, each in their own NSOperation. Each op creates its own SBApplication instance that controls unique instances of InDesignServer. What I'm seeing recently is lots of crashes happening while multiple ops are calling into ScriptingBridge. Shown at the bottom is one of the stack crawls from one of the threads. I've trimmed all but the last of our code. Other threads have a similar stack crawl. In searching for answers, Google's AI overview mentions "If you must use multiple threads, ensure that each thread creates its own SBApplication instance…" Which is what we do. No thread can reach another thread's SBApplication instance. Is that statement a lie? Do I need to lock around every ScriptingBridge call (which is going to severely slow things down)? 0 AE 0x1a7dba8d4 0x1a7d80000 + 239828 1 AE 0x1a7d826d8 AEProcessMessage + 3496 2 AE 0x1a7d8f210 0x1a7d80000 + 61968 3 AE 0x1a7d91978 0x1a7d80000 + 72056 4 AE 0x1a7d91764 0x1a7d80000 + 71524 5 CoreFoundation 0x1a0396a64 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__ + 28 6 CoreFoundation 0x1a03969f8 __CFRunLoopDoSource0 + 172 7 CoreFoundation 0x1a0396764 __CFRunLoopDoSources0 + 232 8 CoreFoundation 0x1a03953b8 __CFRunLoopRun + 840 9 CoreFoundation 0x1a03949e8 CFRunLoopRunSpecific + 572 10 AE 0x1a7dbc108 0x1a7d80000 + 246024 11 AE 0x1a7d988fc AESendMessage + 4724 12 ScriptingBridge 0x1ecb652ac -[SBAppContext sendEvent:error:] + 80 13 ScriptingBridge 0x1ecb5eb4c -[SBObject sendEvent:id:keys:values:count:] + 216 14 ScriptingBridge 0x1ecb6890c -[SBCommandThunk invoke:] + 376 15 CoreFoundation 0x1a037594c ___forwarding___ + 956 16 CoreFoundation 0x1a03754d0 _CF_forwarding_prep_0 + 96 17 RRD 0x1027fca18 -[AppleScriptHelper runAppleScript:withSubstitutionValues:usingSBApp:] + 1036

Since legacyScreenSaver is still the thing running screensavers we make, and it's still buggy, why won't they give us a new template for building screensavers that run in the new engine? And hopefully they don't require them to blend in with the desktop, because most of us don't want that. A wallpaper is a wallpaper, and a screensaver is a screensaver.
