Problem with GUI bitmap border and changing Command property

Hi! (moved this from torque core to scripting since this forum seem more appropriate)

I've searched my fingers bloody for solutions to these two problems.
The first problem is borders around GUI elements. Most elements come with a border which I never asked for and which I can't seem to disable by any "border = 0", "borderthickness = 0" or "border = false" line.
These are not white borders but dark borders. They appear on every element (textMLCtrl, guibitmap) except for the button element. Since the border also appears around the textMLCtrl, I suppose it isn't a problem with the bitmaps loaded.

The second problem I've run into is changing the properties of GUI elements on runtime. What I am trying to build is a system where I can use the same popup over and over, but change the element's properties (like the command property of a button) every time the popup appears. The only way I found so far is to define the GUI elements in a function and then, at the end of the function call pushdialog on the elements. Is there another way to do this or is there at all a way of defining GUI element properties with runtime script (like in a function)?

// Example Code:
function makePopper(%myCard)
{
new GuiMLTextCtrl(popupText) {
canSaveDynamicFields = "0";
Profile = "GuiMLTextProfile";
HorizSizing = "right";
VertSizing = "bottom";
Position = "415 225";
Extent = "190 100";
MinExtent = "190 100";
Border = 0;
BorderThickness = 0;
canSave = "1";
Visible = "1";
internalName = "popupText";
hovertime = "1000";
lineSpacing = "2";
allowColorChars = "0";
maxChars = "9000";
text = $cardPopupText;
border = false;
};
new GuiBitmapButtonCtrl(btn00) {
canSaveDynamicFields = "0";
Profile = "GuiDefaultProfile";
HorizSizing = "right";
VertSizing = "bottom";
Position = "344 152";
Extent = "47 45";
MinExtent = "8 2";
canSave = "1";
Visible = %myCard.mBtn00.mVisible;
border = false;
Command = %myCard.mbtn00.mCom;
internalName = "btn00";
tooltipprofile = "GuiToolTipProfile";
ToolTip = %myCard.mbtn00.mToolTip;
hovertime = "1000";
groupNum = "-1";
buttonType = "PushButton";
bitmap = %myCard.mbtn00.mImage;
};
canvas.pushDialog(Popper);

}
