Users need to resolve graphical glitches and unintended control interactions within Microsoft Access forms.

How to Fix Black Boxes and Checkbox Activation in Microsoft Access

Product: Microsoft Access
Device & OS: not provided
Scenario: Navigating or clicking through controls on a Microsoft Access form or report.
Observed behavior: Controls activate unexpectedly as the mouse cursor moves, or graphical glitches like black boxes appear after a control is clicked.

Before you start

Before modifying your database design, verify if Microsoft Office recently installed any automatic background updates, as sudden graphical rendering issues are frequently tied to new patches.

Solution 1Recommended

Roll Back the Most Recent Microsoft Office Update

If the black boxes or activation glitches started immediately after an automatic Office update, reverting to the previous stable build often resolves the issue.

Microsoft occasionally releases updates (such as on 'Patch Tuesday') that can introduce unintended bugs in Access form rendering. Rolling back to the prior version bypasses the glitch until Microsoft releases a permanent fix.

Disable Automatic Updates

Open any Office application, go to File > Account, click on 'Update Options', and select 'Disable Updates' to prevent the problematic patch from reinstalling.

Open Command Prompt as Administrator

Search for 'cmd' in the Windows Start menu, right-click 'Command Prompt', and select 'Run as administrator'.

Run the Rollback Command

Type the command ""%programfiles%\Common Files\microsoft shared\ClickToRun\officec2rclient.exe" /update user updatetoversion=16.0.xxxxx.yyyyy" (replace xxxxx.yyyyy with the build number of the previous stable version) and press Enter.

Finding Build Numbers: You can find a list of previous Microsoft Office build numbers on the official Microsoft release notes page for your specific update channel.

Solution 2

Inspect Event Properties and VBA Macros

Check your form in Design View to ensure no rogue VBA code or macros are triggering control activation on mouse hover.

Frequently Asked Questions

Why do black boxes randomly appear on my Microsoft Access forms?

Black boxes on Access forms are typically graphical rendering glitches caused by recent Office updates, outdated display drivers, or conflicts with Windows hardware graphics acceleration.

How can I check if a macro is causing my checkboxes to activate automatically?

Open your form in Design View, select the checkbox, and press F4 to open the Property Sheet. Navigate to the Event tab and check if any macros or VBA code are assigned to the 'On Mouse Move' or 'On Got Focus' triggers.

Can hardware acceleration cause display issues in Microsoft Office?

Yes. Hardware graphics acceleration can sometimes cause visual artifacts like black boxes or screen tearing in Office apps. You can test this by navigating to your Windows graphics settings or Office display options and temporarily disabling hardware acceleration.
