In OpsBridge Manager, create a new Page in My Workspace. Create a Vertical Split, with a multi-tabbed Dashboard in top pane. If Dashboard has several rows (example 5), it is fairly large and occupies too much real estate on the page - you need to resize in order to see the lower pane of the Page (drag divider bar). Saving the Page in the re-sized configuration produces no error, however next login the page reverts to original size and needs to be manually re-sized to be usable again. Other Pages without a multi-tabbed top pane *do* save correctly for next session if re-sized. "Save" function seems to not work only for multi-tabbed pages in top.
I opened a support case but was told it was already reported and will not be fixed, then it was suggested to open an exchange idea.
