Fast path - unable to accept or reject chat requests

Hi Everyone,

We are currently have an issue with fast path/spark. When a chat request pops up on a users screen it places the request in the upper left hand corner of the screen and replicates the system tray up the page. (It appears when the chat request should appear). The user is then unable to accept or reject the request. I have tried re-installing spark, but this didnt solve the problem. This started with one user but is now affecting a second.

See the attached screen shot, as the above text maybe confusing.

We are using spark 2.5.8 and openfire 3.7.

Thanks for any help!
