Alt-Click moves browser window instead of turning off snap to grid

Does anybody else experience this?   I am trying to fine tune my align to grid (it is always off no matter how many times I do it). When I try to alt-click to disable snap to fine tune the alignment, my whole browser window moves instead.  It happen on Firefox and Google Chrome.  OPerating system is Linux Mint 18.  

Moved to bugs/tech issue forum... I'm sorry to hear that you're having issues with the site. Could you please carefully work through the first three steps of our guide to Solving Technical Issues ? Step 1: Make sure to use the right browser Please check if these issues persist when using both Chrome and Firefox. Step 2: Ensure that there are no extensions/addons interfering with Roll20 Please disable all add-ons/extensions and anti-virus programs. Step 3: Clear your cache If none of the above succeeds, please thoroughly work through Step 4 . (Don't forget the complete Console Log!) Thank you!

The entire browser window, rather than just the map view within the tab? If that's the case, it's because most Linux systems use Alt for things at the window level, so the Alt+Click is captured before Roll20 ever sees it. (I run Archlinux, and I simply can't do some things on Roll20 because I refuse to rewrite all my keybindings) I found a relevant page  here , although it's for Mint 13 rather than 18. Sorry I'm not more help, but I've only ever used Arch and Ubuntu.

Problem is definitely the OS (well, the OS's window manager). darth_borehd: One thing you can try is to start dragging the image, and then  hit the Alt key. This works for me under Cinnamon.
