I would suggest to display the updated variable outside the ISR routine.
May be set a flag and at main check the flag and then display your variable.
To be honest I do not like the on interrupt. I 'd prefer DT-INTS18.

Re: TMR0 Interferes with I2C GLCD
Thank you for your thoughtful reply, Ioannis. I managed to solve or, at least, work around the immediate problem.
I suppose you are completely correct about moving to DT interrupts. Old habits are hard to break... This is as good a project as any to give it a a shot.
Best Regards,

Re: TMR0 Interferes with I2C GLCD
Well that was easier than expected... Switched over to DT_INTS-18 interrupts. No problems, no hiccups. I have to admit this is pretty darned slick.
Thanks for giving me the push to dive in.
