Not every annual has those, but you'll find the files in the root of the CC3+ data directory, named SUB20xx_Content.fcw

Did you try rebooting your computer after the installation to see if the issue continued after that? I obviously have no idea why this is happening to you, but if something is being done during installation for some reason causes explorer to start crashing, a reboot will at the very least restart every part of Windows.

You should also contact customer support through your registered user pages. Maybe they'll be able to work out something with you, like trying an alternate build of the installer.

Try hitting Tab during the move/resize operation.

I need a cave with some lava for an upcoming encounter. You know the kind, those with open lava pools that only appear in fantasy and isn't particularly realistic, but makes for an interesting gaming scene. I'll be playing around with getting started on this map, as well as show you how to handle exporting it for Virtual TableTop use.

As usual, you can check out the video on YouTube, or watch it in the embedded player here. See the sidebar to see the scheduled time in your time zone, or visit it on YouTube where you can also see the schedule, as well as set a notification for when I go live.

If you have access to Acrobat Professional, it may also be worth trying to feed it through the PDF optimizer, flatten the structure of the file.

Those old PDF's are pretty cool, because they contain actual vector data from CC3+, making them have the same "infinite" zoom capability that the original CC2 map it was made from. But unfortunately, that also means it is highly complex, which is why it probably crashes your readers now.
