Following the docs I’ve always set the ProgressBar.Maximum to 0 if I want a ProgressBar to appear indeterminate. This has been working fine under Windows but I’ve just started work on the OS X version of my app (in Yosemite) and setting ProgressBar.Maximum to 0 shows the ProgressBar at 100% and without the “barber pole effect” that would indicate an indeterminate ProgressBar.
Am I doing something wrong (likely) or might this be a Yosemite/Xojo thing?
