This is a problem of scale.
You should use fixed point math for picoliters(e-12) and milliliters(e-3), etc.

When I have weird behavior, I'm forced to simplify the code and/or write info to log files before crash. I use prototypes instead of CallFunction. Then inspect each prototype for valid address. I use threads and semaphores, but never threaded variables. My databases are under 1GB. So far, v6.10b6 is...

[ctrl] and [alt] have no real action by themselves so what are you trying to accomplish? Here is mousemove + [ctrl] or [alt] on the canvasgadget. #CG = 0 #EV_KS_CTRL_T = 100 #EV_KS_ALT_T = 101 #EV_KS_TAB = 102 OpenWindow(0, 0, 0, 500, 500, "Canvas Keyboard Shortcuts", #PB_Window_ScreenCent...

I don't understand your requirement? I use dozens of keyboard shortcuts with the canvasgadget. #EV_KS_CTRL_T = 100 #EV_KS_ALT_T = 101 #EV_KS_TAB = 102 OpenWindow(0, 0, 0, 500, 500, "Canvas Keyboard Shortcuts", #PB_Window_ScreenCentered | #PB_Window_SystemMenu) CanvasGadget(0, 0, 0, 500, 50...

Don't mess with the mouse.
Change the idle state.

There should be an api or dll you can poll for the barcode reader input?
How you choose to display in your gui depends on where you put the user focus.

System languages needed pointers to be efficient.
Even Fortran added pointers later.
Basic had clunky varptr() and addressof().

Yes, C++ became a bloated mess with technical debt and over a 1000 pages of definitions.
But, you can still choose to code C++ with a C approach and do very well.

Most languages have C interoperability anyway.

Semaphores can signal other semaphores.
My main loop (gui) never attempts to touch the threaded data until a thread posts an event.

Is there a significant speed improvement with map access using integer keys?

I prefer semaphores since they are more flexible. And I can effectively lock data with semaphores, without adding mutexes.
I cannot signal multiple threads with a mutex.

Wow! Thanks for SQLite update.
Not loving how laborious installing MS Visual Studio Community Edition has become.
