Hello, 

Using MS Access 2013. On my forms I have a command button to refresh the page data, so that new data can be entered. 

They were working fine, but then one day stopped working and I cant figure out why. The other buttons on the forms work (save data, etc) and Ive tried deleting and making a new command button, still doesnt work. I know the form is refreshing because the time gets refreshed. 

Any idea what changed? 

Hi,

As far as I know, Form Controls (FM20.dll) are no longer working as expected after installing MS14-082 Microsoft Office Security Updates for December 2014. This might be the reason.

Please try to install the hotfixs that released in the March 2015.

If this issue still exists after installed hotfixed, I recommend you post the question to Access forum to do further troubleshooting.
