Hi,

1)

Every so often users get this normally with the File menu. Visual Micro has to ask Visual Studio if a menu item exists already before it is created. Visual Studio is saying that it does no when we know it does.

There are sometimes things we can do to get around this problem. For example the File menu also suffers from the problem but we recently added some code to try to detect the problem other wats. for the next release we will try the same for the Project menu

Workarounds

In the latest release of Visual Micro you will see the "Tools>Visual Micro>Reset User Interface" menu item. This cleans up the Visual Micro user interface and we are recommending it be run once after upgrading to 1309.04+. This is because there have been some menu syntax changes but probably won't fix your problem. It will remove duplicates but you have created a script for that anyway.

There is one thing you can do not to fix but to hide the problem. Change your VS 2008 shortcut to include the "/resetaddin" command. This will clean the visual micro interface each time vs 2008 starts. Not ideal but an option. 

Shortcut Example

[path to devenv.exe] /resetaddin Visual.Micro.Visual.Studio.Arduino.Helper

...

2)

As an aside, I noticed a bug in VS 2008 with the latest release. An intellisense message (C++ Compiler Error) appears when you first start or change board. This will be fixed in a service release over the next few days and prevents intellisense from working fully.

Thanks for the report
