File takes forever to open/close

I created a timesheet template for hourly employees at my job. Every pay period they email me their filled-in timesheets. Each Excel file contains 24 sheets, one for each pay period of the year. Each sheet contains about 50 checkbox userform controls. Here's my problem:

When I open or close the file, it takes forever for the hour glass to disappear. I believe the checkboxes are to blame. They are somehow using up too much RAM for my computer to upload quickly, even though I have a fast computer.

When I open the file, I don't want to make changes or to recalculate anything. All I want is to see the timesheet and print it out. Is there a way to turn off the checkboxes or instruct Excel to not upload the checkboxes. Maybe then the files will open quickly.

Forms and Controls checkboxes are major overkill on worksheets. Search for Marlett Checkboxes here and on http://www.ozgrid.com/forum. Very easy implement and use.

Thanks for the info. I never heard of marlett boxes before. Attached is a file showing what I've done. I created the marlett box and assigned a macro to it, but now I'm unable to untick the box. Can marlett checkboxes work with macros? The macro in this sample deletes cells A2:A4.

Thanks for the tip. I'm incorporating your macro and experimenting with different modifications. Everything good so far.
