Click on desktop object strange behavior...switches positions with another

Question

Boy, how am I going to explain this...I find my system sometimes does the following.
I click on an object on the desktop...one click and it transposes itself with another object. If I click on in the same location (the transposed object)...it transposes with the original object...over and over again. I can click on other objects and they sometimes with transpose with other objects.
For those of you old enough to watch the old TV show CONCENTRATION with the flipping tiles...it feel like that.
I have NO IDEA what is happening or how to fix it.
Thanks, --bill

So:

Should read:
<cfset "VARIABLES.#a#" = masterQuery["#a#"][1]>
Could be better, much better! The following are just string assignments:
<cfset "VARIABLES.#a#" = masterQuery["#a#"][1]>
<cfset "VARIABLES.#a#" = evaluate('masterQuery.#a#')>
They contain a lot of complexity for the sake of complexity! A variable assignment would have been much better.
Let us therefore dissect the code. Consider the loop you reference:
<cfloop list="#masterQuery.columnList#" index="a">
        <cfset "VARIABLES.#a#" = evaluate('masterQuery.#a#')>
</cfloop>
Assume that the columnList consists of "col1,col2,col3". Also assume that the query returns the following data:
      col1 | col2 | col3
row 1: v11 | v12 | v13
row 2: v21 | v22 | v23
row 3: v31 | v32 | v33
row 4: v41 | v42 | v43
Then the loop will run 3 times, since columnList has 3 elements. The attribute index="a" implies that the variable a will successively take the values "col1", "col2", "col3" at each pass of the loop. The value of "VARIABLES.#a#" will therefore be, successively, the strings
"VARIABLES.col1"
"VARIABLES.col2"
"VARIABLES.col3"
Likewise, the variable evaluate('masterQuery.#a#') will take on the respective values
evaluate('masterQuery.col1')
evaluate('masterQuery.col2')
evaluate('masterQuery.col3')
These are, by default, the values of the first row of each column, hence:
v11
v12
v13
So, what your loop actually does is as follows:
First pass: 
     "VARIABLES.col1" = v11
Second pass:
     "VARIABLES.col2" = v12
Third pass: 
     "VARIABLES.col3" = v13
You are essentially picking out the values of the first row! It would have been much simpler, and neater, to do something like this instead:
<cfset firstRowData = structNew()>
<cfloop list="#masterQuery.columnList#" index="a">
        <cfset firstRowData[a] = masterQuery[a][1]>
</cfloop>
