Is this a Filter Forge or MacOS issue, anyone?

I recently opened my Filter Forge to refresh my Filter Editor skills only to be greeted with an impossible read and functionality.
Not only is the Workspace upside-down, it is also mirrored. [See Image below for full understanding]
All mouse interactions within Workspace is the same and extends into the Colour Picker pop-up window.
For those curious, this is FF7 and it worked fine 3 years ago, prior to a head injury that left me unemployable.
Upgrading is difficult as I am still financially restricted.

Just wanted some feedback regarding FF or MacOS issue, as I can VM an older Mac version if there isn't a FF patch for this.

Current MacOS: Sequoia 15.7.2 (Intel)

It was an OSX thing. Apple had updated their os and things broke. Here is a post from a while back when this issue came about. Upside Down interface
