First, I attempted to edit an older file that I had just finalized the previous day. It refused to load, and I was forced to shut down my computer to regain control. I spent over an hour trying to recover anything, as it was a 16-page, dense text document. The only thing I could safely accomplish once I started OO was to immediately shut it down.
Next, I erased v4.1.15 and installed the newer v4.1.16. I opened a text document and found it had the same problem! When I opened the text document, I attempted to set the Page parameters, only to have it lock my computer up solidly. I again had to power down my system to regain control.
Third, I erased the v4.1.16 and reinstalled v4.1.15 not only to verify that a new install still had problems but to make sure none of the "update" weren't causing problems. It still refused to run.
At that point, I had run out of options, so am now being forced to embarrass myself on the forum once again by admitting my lack of useful knowledge. I tried to upload a DxDiag.txt file, but it was too large. File size:171,265 bytes. Size on disk: 172,032 bytes.
I have 65536MB RAM, an NVIDIA GeForce RTX 5090 with 32101 MB Dedicated Memory and 36993 MB Shared Memory running 3440 x 1440 (32 bit) (240Hz) resolution on a Displayport connection to my monitor.
OK, I removed all the device driver information, because I just update every time it's required. I can add that to a later post if required. Now, the shortened DxDiag.txt file has been added as an attachment.
Please help, as I am 77 years old (I know, not relevant) and I suffered a stroke a few years ago and find OO extremely useful in creating legible text documents rather than being forced to write anything out.
