User is logged into Remote Desktop Services running on virtualised (VMWare esxi) Windows Server 2012 Standard. They could be typing something into a dialog box and it starts out in lowercase and then suddenly the caps lock key activates and it starts displaying the typed letters in uppercase. The caps lock light indicator on the keyboard remains off. Press the caps lock key and the light indicator turns on and the typed text is in lowercase. Minimise the RDP screen to taskbar and maximise the screen "corrects" the state of the caps lock.
This issue happens intermittently I have multiple users that have experienced this problem, but for one user it happens on a regular occurance (at least half a dozen or more times a day).
Changing computer, keyboard and mouse. Changing operating systems (happens with both Windows 7 and XP). Updating RDP client under both operating systems. All the research that I've done relates to either Windows 2000 or Windows 2003 operating systems.
