I have a strange problem.
At home my DNN 4.9.2 site works fine on Windows Vista. I can log out, I can update a module and the updates are displayed instantly.
At work, on numerous XP machines across numerous browsers (firefox, ie, chrome), I cannot log out on first attempt. If I click logout 4-5 times, it eventually will log me out... but if I close the browser and re-open it, I appear to be logged in again. Additionally, if I update a module (i.e. HTML module), the updates take a few minutes to appear, even if I hit refresh. If I "Edit Text" on the recently updated module, the old un-updated text is present in the FCK editor.
At work, I can log out from a DNN 4.9.0 site just fine (one I haven't upgraded yet).
Any thoughts? Is this a problem with XP? I changed my cookie timeout settings to the default values, still nothing. Cache settings unchanged. Tried clearing cache. Is it a problem with the firewall/settings on the work computers? I am at a loss for what is causing this issue.
