Here's the latest. I have tested this on Chrome, Firefox, and IE. I've tried the latest revisions of galaxy-central (71031bf3105c) and galaxy-dist (26920e20157f) straight out of the box (hg clone, sh run.sh, go to localhost:8080). I am still running into same issue. All is well with 19 or less datasets in the history, but as soon as I add a 20th I can no longer run a workflow on multiple datasets. Are there any known issues running galaxy on Ubuntu 10.04? ________________________________ This e-mail message (including any attachments) is for the sole use of the intended recipient(s) and may contain confidential and privileged information.
