This actually applies to all three programs in the Suite. The color picker in CMYK when used in click-and-drag mode,  runs into a problem with its local readout when the first two elements (C,M,) are both 100. When that happens, the field length for the readout does not expand far enough, and the K value is truncated at one or two digits, depending on the number of digits in the Y value. When that happens, the only way to get the accurate K reading is to let go of the mouse, so the full set of readings appears in the palette on the side. But this is quite a nuisance when it happens. I've made the attached screen capture video to demonstrate. 
This is in Windows 8.1, using a 1920 x 1200 monitor.
The video is in .MOV format. If it doesn't run properly, I'll upload another one in a different format. Let me know if it's necessary.

I followed the instructions in their crash report. I deleted preferences and cleared the cache. Restarted. Did this multiple times. No help. Quark support has already been in touch with me, asking for files.

I'm trying the entire suite in trial. Finding lots of problems with Publisher, trying to work on large documents in novel format (6x9 trade, 700 pages). Nastiest problem to date: inserting a page in a two-page spread. The imported material, from a Word Docx file, does not have the necessary blank pages before a new chapter most of the time. (The imported file was used to create an Epub file, which does not need the blank pages.) In print format, the standard practice is to have a blank page, or a page with a fleuron, on the verso, and the new chapter page on the recto, in those cases where the previous chapter has finished on a recto. As you will see by the attached PDF, the blank page is inserted all right, but then the margins go haywire. In Quark the margins automatically adjust. In Affinity Publisher, the verso margins are now attached to the recto page, and this carries on for the rest of the text.
And by the way, this happens whether or not the material has been imported using File>Place to import the text directly from Word, or the material has been copied and pasted without formatting.
This one is a deal breaker. The program is not useful for trade novel layouts when it has a bug this serious. There are lots of others, but I managed to find workarounds for most of them. For this one, the only workaround is to go page by page and reset the margins. And then another page insertion (or deletion) might undo everything again.

I guess I didn't make myself clear. That was the page I got by following Walt Farrell's link. If you go into the main pages that list the programs, and click on "Buy Now," you will find lilnks for the free trial to Designer and Photo, but no such link for Publisher. The "Buy Now" link in Publisher brings up what you see on page 3 of the PDF>
