Over the past couple of days, I've been having trouble accessing my current histories in the galaxy GUI. I'm fairly certain I have no jobs waiting to run, and my data usage is only at 38%. But, whenever I attempt to switch between histories, I'm unable to access any of my data. Eventually the current history will show its contents but this takes hours, and nothing else will load. I can't even access any data sets from the user drop down menu, even though all currently active sets are listed. I've never had trouble using different histories for individual replicate analysis before. Does anyone have any suggestions on how to remedy this?
