Hi there, all. I see with the mop beta. i cant move this frame no more. i have looked into other ways around this. but something i am missing that has changed with mop. any help would be great-full. thanks

Code:

local f1 = CreateFrame("frame", "wStuff", UIParent)

f1:ClearAllPoints()

f1:SetPoint("CENTER", UIParent, "BOTTOMRIGHT", -500, 30)

f1:SetWidth(189) f1:SetHeight(65)

f1:SetBackdropColor(54/255, 54/255, 54/255)

f1:Show()

f1:SetScale(0.8)

f1:SetFrameStrata("LOW")

f1:SetBackdrop({ bgFile = "interface\\Tooltips\\UI-Tooltip-Background", edgeFile = "Interface\\Tooltips\\UI-Tooltip-Border", tile = 1, tileSize = 26, edgeSize = 26, insets = { left = 3, right = 3, top = 3, bottom = 3 } });

f1:EnableMouse(true)

f1:SetMovable(true)

f1:RegisterForDrag("LeftButton")

f1:SetScript("OnDragStart", function(self) if IsShiftKeyDown() then  self:StartMoving() end end)

f1:SetScript("OnDragStop", function(self) self:StopMovingOrSizing() end)

f1:SetUserPlaced(true)
