Sometime between 12/9 and 12/13/21, I lost some of my tools (both down the side and above) and the PDFs are generating with about a 1/4 to 1/2" of additional border beyond the prescribed boundaries of the documents. I tried resetting my toolbox to default, but I don't see any difference, and I have no idea what to do about the PDFs. Incidentally, the PDF files have been huge ever since I upgraded to CorelDraw 2019. Whenever I'm doing a 12-page color newsletter, I have to have the guy that posts it dumb it down in the extreme! Before that, I could keep an online document under 20 MB at 150 dpi, but now it's over 50 MB. If I generate one at 96 dpi or below, it comes out fuzzy.
I have read that Microsoft 10 updates have been messing with a variety of programs and I have the dates (above) when it could've happened, but I don't know how to track down which update(s) might be the culprit(s). Years ago, I had an MS update screw up my PageMaker, but I knew the exact date when it happened and there were forum postings on it, so I was able to fix the problem. Thus far, I haven't found any for my issues.
It also occasionally does a bizarre thing on a 12-page newsletter, where it starts flashing little object handles all over the place and eventually, facing pages swap places (I shot a video, but it's too big to post). Every once in a while, it does more than just swap facing pages and I end up with misplaced pages all over the place. I had the same problem with the previous version and the tech had no idea what do about it, and naturally suggested the upgrade. But guess what? It's still doing it! Just not as often...so far.
Yes, Windows updates can cause the most peculiar things to happen.In this case though, It sounds more like Draw has been corrupted somehow.I suggest you try the Repair option from the suite's install routine.Regarding the PDF's getting bigger than normal, I'm pretty sure it is just an export setting.There's a number of things that can make the files grow, like for example bitmap compression.Also remember that some Draw specific effects may be rendered as bitmaps depending on your export settings.
One more thing. I located the Microsoft update that occurred between 12/9 and 12/13/21 and it's Servicing Stack 10.0.19041.1310 (Release date November 9, 2021—KB5007186 [OS Builds 19041.1348, 19042.1348, and 19043.1348]) Apparently Service Stacks can't be uninstalled...at least not by lay folk.
