Access 365 Runtime 2605+: MsgBox in Click event stops responding (Zoom related)
Starting with Access 365 Runtime version 2605 (build 20026.20168), MsgBox called within a Click event stops responding under specific conditions. We have confirmed that the issue is related to the Access Zoom feature. Microsoft 365 support advised us to report this issue in the community, so we are posting it here. ■ Affected Versions No issues confirmed prior to May 2026 Version 2605 (build 20026.20168) and later → Affected ■ Reproduction Environment Access 365 Runtime Resolution: 1920×1080 (Full HD), Text size: 100% Issue does NOT reproduce at text size 125% or 150% ■ Sample File We have a minimal sample database (Db1.accdb) that reliably reproduces this issue. It contains two forms (Form A and Form B). We can provide it on request. ■ Steps to Reproduce Open the sample database → Form A opens Click Button A on Form A → Form B opens Click Button B on Form B → MsgBox appears (works as expected) Click “No” in the MsgBox Click the Close button on Form B → Form B closes Click Button A on Form A again → Form B opens Click Button B on Form B → MsgBox should appear, but Access stops responding instead Pressing the Alt key resumes execution and MsgBox appears Note: MsgBox displays correctly the first time Form B is opened (step 3). The issue occurs after Form B has been closed and reopened (step 7). ■ Findings Enabling “Disable zoom” in File → Options → Current Database prevents the issue. This option is available in version 2608 and later. The issue also does not occur if Form A is moved to the far left of the screen, or down to approximately the vertical center of the screen, before performing the steps. ■ Temporary Workaround for Versions 2605–2607 The “Disable zoom” option is not available in these versions. Adding the following code immediately before the MsgBox call avoids the issue: Application.Echo False DoEvents Application.Echo True However, this workaround causes side effects in some forms of our application, such as unexpected termination and unexpected parameter prompts for record sources, so it is not a suitable long-term solution. ■ Request This issue began occurring around May 2026 in an existing application whose code has not been changed. We kindly ask the Access team to investigate and fix this issue so that it does not occur when Zoom is enabled. If anyone else is experiencing the same issue, please let us know. We can share the sample file on request.
Run-time Error '3340'
Hi, I have a client who got the error today however they don't have Office installed, instead they are using the 2016 Access Runtime. They only had 2 updates on Nov 13 but they were security update related to Windows and nothing for MS Office obviously. They uninstalled one of the updates which didn't solve the problem and Windows 10 wouldn't allow them to remove the other update. Now I don't know where to go, any chance anyone might know the answer? Thanks Rob
