Regularly, when I am using **Photoshop CC 2018** (mostly) 
suddently I got a **modifier key** who **stay always activated**
sometime it is the **COMMAND** key, or sometimes the **SHIFT** key
which make **impossible to work** with these kind of applications using intensly the modifiers keys for almost anything...

The only way is to reboot, but even so, I suspect that when I have rebooted and relaunched Adobe Photoshop, the mean bad appends very quickly, so very hard / almost impossible to work

Here is my setting :
**MacPro 4,1** (Nehalem) with **Mac OS X 10.11.6** El Capitan
and the **Adobe CC 2018** suite///

also, I have a **WACOM INTUOS 4** Tablet, (actually with driver **6.3.32-4**) BUT I got the bug since several previous version of the wacom tablet driver
and (suprise) a mouse and a keyboard.
worth mentionning : the keyboard is actually a **window keyboard**. but it didn't need any driver to install. I just got few key not related to mac function, but even the F1 to F15 key function work as intended by apple when using it with the FN key (SOUND UP/ DOWN / MUTE and misssion control etc...)

**Please** is anybody can help me plizzz ?!

**Thanks** **very** **much** in very advance !
Tell me if you need a EtreCheck Report, (?)  if so I can quickly post a link of my current report.
