Known Issues
This page is Tricerat's registry of acknowledged issues: defects, limitations, and external breakages we know about, with their status and where the fix or workaround lives. If you're wondering whether the problem you're seeing is a known product issue, check here first. Security advisories, like our response to a Microsoft CVE batch, live in Security Advisories. For step-by-step diagnosis of symptoms that aren't listed, the troubleshooting guides are the procedure library — and version-specific issues appear in each release's release notes.
Long-Standing Known Issues
These apply across current ScrewDrivers v7 releases and aren't expected to change in a near-term release.
Report viewer overlays dialog windows in ScrewDrivers Administration — If the active tab is Reporting, the report viewer hides portions of the File→Options and Help→About windows due to a technical limitation. Workaround: switch to another tab before opening those windows. We don't expect this to be fixed in a future version.
Compatibility and Third-Party Issues

Something not listed?
If your issue isn't here or in the troubleshooting guides, it may be new or specific to your environment. Check that you're on the latest release first — many issues are fixed in point releases (release notes) — then contact Tricerat Support. Support can confirm whether behavior you're seeing is known internally and will make sure genuinely new issues get documented here.
