Hi again Joe
As WBI doesn’t itself use any AyaNova related files that are physically on the computer, instead it is web pages from the server’s WBI that are loaded on that commputer’s browser - based on your troubleshooting so far that it doesn’t matter who you log into WBI as on these two computers, that there is something specific with these two computers that is causing this.
What you now need to do is troubleshoot what is the same about these two computers compared to computers where this does not occur, and go from there - for example:
What is the browser used on these 2 computers?
What is that browser’s version?
What is the display adapter on these 2 computers?
And the driver used with this display adapter?
What is the color quality set for the display adapter - 16bit, 32 bit, etc?
It could be that the browser in use is corrupted or has an issue that needs to be fixed. It could be that the display adapter driver needs to be re-installed or updated. It could be that you have the color quality on the display adapter set to below 32bit. Do check these out and post back what you find
