Cannot resize the graph window after updating to 26.10

Thanks, this was a bug in 26.10. The graph drawing was rewritten in this version, and when the graph window has no title bar, the new graph covered the edges you would normally drag, so there was nothing to grab.

It is fixed now. The version number stayed at 26.10, so the update check will not offer it. Please simply download the app again from NetWorx page and install it over your current copy. Your settings and data will be kept.
