I'm hoping someone can help me with the following. A week ago, I upgraded my computer from Windows 7 Pro to Windows 10 Pro. All went well, and amazingly almost all my programs continued to work. That includes HyperSnap, a wonderful screen capture program that I've used for a zillion years or so. Today, when I started my computer, I saw a message on my screen that said that the following key combinations no longer work: CTRL-Shift-C, H, R, and X. The message also said "They may be in use in another program." The only one I'm concerned about is CTRL-Shift-R, which Hypersnap uses to capture part of a screen. I use it a lot, and I've used it several times since upgrading to Windows 10. But today it no longer works. When I use CTRL-Shift-R, nothing happens.
I'm wondering how best to deal with this. Can I re-set things so that HyperSnap controls CTRL-Shift-R? If so, how? Is there a way to find out which program currently has usurped that key combination? Though I'm very reluctant to switch to a different key combination after using the same one for many years, I'd like to know how to do that if I have to. Which is to say, how do I find out which key combinations AREN'T currently being used by anything on my computer? With so many possibilities, trial and error doesn't seem very practical. I've googled (or, rather, Duck Duck Goed) and have found lots of lists of Windows 10 shortcuts and one site that listed 12 programs that use CTRL-Shift-R, including HyperSnap. A few are programs I have on my computer (e.g, Microsoft Edge, Mozilla Thunderbird, Firefox), but none of them were added in the last couple of days, and none of them interfered with HyperSnap's using that key combination when I used it up through yesterday.
I should add that I ran my daily security scan with Malwarebytes, and it came up clean.
I'd be most grateful for any suggestions/information you're able to offer.
