Userform Controls Behaviour When Moving From One Control To Another

I have built a quoting tool and Userforms to act as a user interface to this tool. The userforms basically just feed user input back to relevant sheets. I have a number of textboxes, listboxes and radio buttons on multipages. Now the issue is that each control has an Afterupdate or Change event associated with it. Consider this scenario:

I have 4 product categories (represented by radio buttons) : Cat A, Cat B, Cat C, Cat D

Each category can have up to 10 line items which are represented by combo boxes.

Now lets say the user has selected Cat A radio button, he selects a product from the combo box (the cursor or focus is still on the combo box) and clicks on Cat B radio button. Here is the issue: on the first click, Afterupdate or Change event of Combo box fires but radio button is still unselected. The user has to click Cat B radio button AGAIN to select Cat B radio button. So essentially it takes two clicks with a slight pause between them to change categories.

One way to avoid this is to press Enter or 'tab through' each field. But this is not very intuitive. I have tried using Exit, Afterupdate, Exit, Change events without success. I can't use ControlSource option because the cell to input info to is dynamically selected. I have used xlCalculationManual for some text boxes but can't use this since some inputs on the userforms depend on the right value being calculated on the sheet.
