#8245 closed defect (fixed)

Plugin does not work with Chrome 7.0.517.44 on OS X

Reported by: kisielk Owned by: jun66j5

Severity: normal Keywords:
Cc: Trac Release: 0.12


As advertised is it should work with Chrome 4+, but it doesn't seem to work Chrome 7.0.517.44. The drag-and-drop enabled message only appears when I test with FireFox.

Which revision of the plugin do you use? In [9288], I fixed the problem that does not work with Google Chrome 6+. If possible, try the latest.

Sorry for not answering earlier. We're using r9355, so it seems the fix in r9288 didn't do it..

Now, Chrome was dropped gears and the browser doesn't have xhr.sendAsBinary() method.
See .
So I made a simple patch to fix it.
