I'm not sure what component you refer to. TAdvSpinEdit does not have its own context menu in our code, it is the standard Windows context menu for an EDIT control class that appears. We are not aware of any issues with this context menu. As it is a Windows context menu, it can also not be turned off. Is this unique to TMS edit controls? Did you test this with regular VCL controls? If a problem persists with this and it is uniquely related to TMS controls, please provide some sample source app with which this issue can be reproduced here.
