DSPCB 8 grid bug

After using DSPPCB 7.x for some time, I have just installed and started to use DSPPCB 8.

Straight away I hit a problem whereby, in PCB view, depending on how the grid menu is accessed, changes to the working grid are not saved:-

If you change the working grid using the menu obtained by clicking on the 'Grids' icon, then the display is updated with the new grid as expected. However, this change is only temporary: As soon as you move a component or refresh the view, it reverts back to the previous setting.

However, if you change the grid from the menu obtained under 'Settings', then it works as you would expect and the change is saved.
