Another install on my Aspire one netbook
Can I ask how you have made you mint menu transparent? I've googled this and can't find a how to.
I'm using LM10 Gnome (and I'm not sure if this is a limiting factor, though I don't know why it would be as LMDE also uses Gnome).
Sorry, think I have found it!
This can be set in the preferences of each item.
Right click the Menu icon, select Preferences, select the <Options> tab and the Opacity setting is at the bottom.
Open a terminal, select the Edit menu item, select Profile Preferences, select the Background tab and the Transparency slider is at the bottom.
