Display Computed Structure (bug?)

[JeremyMCarr]

Hello WebMO Friends,

The most recent (V25) update on the common server feels buggy. When my students and I run optimization calculations (Mopac or Gaussian) and then display results, ~50% of the time the optimized structure does not display; the molecule screen appears blank. The raw output file does appear. Browser doesn't matter. This wasn't an issue with V24. It's reminiscent of previous versions that used Java.

The only other thing I can think of was I just updated to the newest Sequoia OS, but many of my students have not and we're having the same issues.

Any similar issues?

Thanks :-)

This is almost certainly related to Javascript caching issues, causing a mix of old (outdated) and new (updated) Javascript files to be used. The solution is to clear the browser cache via "hard" reload. In Chrome this can be done as:

* Press F12 (or Ctrl-Shift-I) to open the Developer menu.
* Press and HOLD the normal “Refresh” icon, which will open a sub-menu.
* Select “Empty Cache and Hard Reload”.

We are working on a small updated that forces the browser to clear the cache automatically on upgrades.
