We are currently running Smartermail Enterprise v13.3.5535. By buttons I mean [NEW], [ACTIONS], [DELETE], [VIEW], [REPLY], [REPLY ALL], [FORWARD], [DELETE], [ADD], [VIEW], [PRINT], [CONTACTS], [CALENDAR], [TASKS], [NOTES], [FOLDERS], [REPORTS], [SETTINGS], [SEARCH], etc. All other functions work fine, like clicking on an email brings up the email in the preview pane.
The only commonality with the three workstations at this physical location is that they are using Satellite internet, as they are in a very remote geographical location (population 15 with only another 1000 in the entire county). Could d/l speed be affecting the buttons in Smartermail webmail? Strange thing is that Smartermail webmail worked fine for them at this location on that connection for a year and just started not working as of last week. The only change in the past week on these computers was a Quickbooks Online update, and all browsers had critical security updates in the past week. Could that cause a conflict in all web browsers? Anyone have any ideas what could be causing this?
