Whole excel ribbon 'Freezes' when programmatically opening a file

Hi,

When programmatically opening a new xlsx file via the below method, the whole ribbon becomes frozen (un-clickable) until deactivate and reactivate the newly opened Excel instance. After that, the ribbon works as it should. 


var workbooks = ExcelApp.Workbooks;
var workbook = workbooks.Open(filename);

Marshal.ReleaseComObject(workbooks);
Marshal.ReleaseComObject(workbook);


As I've only been using Addin Express for a week, my best guess is that it's either that I'm not releasing a COM object related to the Addin Module or Ribbon itself, or maybe I'm not using the correct method to open a file.

Thanks in advance.

I've figured out the problem. It was due to leaving a manually created dialog window open while opening the new file. Closing the dialog before calling workbooks.Open(filename) was the fix.
