This plugin is a great fit for our requirements and seems to work well except for a couple of issues.
This is a buddypress installation. It was working well for several sheets that we created. Logged in as admin and editor.
However as of sheet ids 7 (not working) and sheet 8&9, for IE 8 & 9 the rendering of the sheet shows the top icons down the left side of the sheet and the CSS formating is gone. Same view in Chrome and FF are good and workable.
The IE views will not allow picking of any cell for editing. From what little HTML I could investigate it looks like CSS call is broken when logged in as an admin/editor. When logged out the formating returns when the edit icons are removed.
Note that the width is adjusted to 577 px.
Summary only in IE when logged in to edit does the rendering fail.
Side note, when attempting to create id 7 and adjust the column widths, something happened (unknown) that caused the sheet to go completely white with no data or formating. Attempted to delete from database and reestablish, but still no luck. There were three data table that I edited, did I miss one or is there someplace to look for a call that would be blocking the plugin from starting a new sheet?
