Windows – Synergy prevents click and drag actions in some Windows applications

64-bitimacmousesynergywindows 7

My Synergy setup is a Windows 7 x64 server and an iMac client.

The problem I'm experiencing is that Synergy prevents click and drag actions in 'some' Windows applications.

I notice it most often in Photoshop – while Synergy server is running I am unable to apply a mask or use any paint or rubber tool for more than a single click.

The problem also occurs to a lesser extent in other programs, i.e. in MS Word I am sometimes unable to highlight text using the mouse – no problem if using the keyboard though, and since I mostly use the keyboard it doesn't bother me so much, however rearranging the text with a mouse is difficult.

Understandably its somewhat irritating to have to quit Synergy – which otherwise works perfectly – just to apply a mask or rearrange some text.

The problem goes away the moment I close Synergy server and comes back when I start it up again.

Anyone have any ideas how that might be fixed or is it a bug?

  • It is a bug, and is normally caused by "stuck keys" (when Synergy is mistakenly telling the OS a key is being pressed when it isn't.) Usually having the Escape key stuck prevents dragging and dropping. Workarounds for this are varied, but for me (with a Windows client and Linux server) pressing all the modifier keys one by one while on the client screen (alt, shift, ctrl, win), the escape key, and also pressing alt+ctrl+pause (to bring up the Windows alt+ctrl+del screen) and escape fixes the problem (until the Windows PC is next locked with Win+L or by the screensaver.)
