I am trying to select the column in Spreadsheet and when I try the entire sheet keeps moving. I tried this in Chrome, Edge and IE and able to reproduce. I tried with my colleague and works fine for him. What could I be doing wrong?
IMHO, if the problem only in your client, probably it is related to your computer. But, I have no idea about the solution. Here is the repo of the Collabora online integration app: https://github.com/owncloud/richdocuments . You can create an issue about your problem with reproducing steps to get help.
hmm, I newly notice that the subject opened long ago. You can try the update your collabora app also.
