This is my own doing and no reflection on Xara.

I previewed a page in Xara and clicked the Edge icon as per usual. Now, I'm testing the Edge Chromium beta and I know it doesn't work for Xara previews, so when asked which browser I want to use I usually click Edge but leave the option to test Edge (dev) there because every weekly update I try it. Today I tested it again but stupidly left the tick in the Always Use option. It, unsurprisingly, still doesn't work with Xara preview...but I don't know how to get Xara to ask me which version of Edge to use anymore.

I tried swapping the default back to Edge, and I know I could uninstall the dev version, but I don't want to reset all the settings I've made. Therefore, I finally get around to my request. Would anyone care to take a stab at how I can get Xara forget which browser I told it to use?

Not your usual question and I don't expect this has been asked before either.
