As I said, I basically wanted to report a problem. What should I do now?
If it's a reproducible problem where by giving steps to reproduce anyone can duplicate your issues, then you can file a bug report.
However first you need to find out if this really is a general problem or something system-specific. Contacting support would be what I'd recommend as a first step so they can help narrow down the source of the problem, then how to fix it.
I have X1, X2, and X3e installed on my computer as well as 8.5 and Platinum, but don't run into issues with program handling. However I have switched over almost exclusively to 64-bit plug-ins, which probably helps.
