I'm happy to report that ChemWriter now runs without known issues on Chrome for Linux and Windows.
As reported here previously, SVG on Chrome for Linux and Windows suffers from a known bug that prevents attachment of event listeners to SVG DOM elements under certain conditions. Fortunately, the bug was pinpointed and a simple XHTML file can be used to reproduce the behavior.
Although Chrome recently pushed Version 9 to clients, this update unfortunately didn't fix the problem.
I won't go into how we enabled the workaround here. Suffice it to say - ChemWriter can now be used on all desktop browsers with a significant user base, with custom interfaces for iPad and Android tablets coming soon.
