The HTMLViewer is dead simple. I tossed one into a window as a test of something else and never expected it to not work... but it didn't. I reviewed my code and compared it to the sample code in the language reference. All good. Still wouldn't work.
I then opened up the SimpleBrowser example project that ships with Xojo 2019 Release 1... I did nothing to the code and attempted to run it as is... didn't work.
I'm using Xojo on a MacBook running Mac OS X 10.11 (which should totally be able to run 64-bit everything, right?) but on a whim, I decide to change the build settings from 64-bit to 32-bit, ran the project and... I'm looking at wikipedia!
Is this a bug? Anyone have any idea why this simple control won't operate in 64-bit?
