I have this message show up on Headquarters Manager evertime I try to copy something to my clipboard. It says it cannot open clipboard and then proceeds to close out Headquarters Manager. Any suggestions?



Thanks, Andy Pinney

HI, Increase the number of clipboard retries. Something like 50,000 How you accomplish this: (be alert this is really hard job take the registry backup)

  1. Create the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\Current Version\Terminal Server\Compatibility\Applications\{app name}

where {app name} is the name of the application without the extension.

  1. Add the following registry values to the above registry key:

OpenClipboardRetries: REG_DWORD: 0x20 OpenClipboardDelayInMilliSecs: REG_DWORD: 0x50 Flags: REG_DWORD: {num}

Let me know if it works
