R help - Jan 2012 - Error from Brugs "'r for windows gui front-end has stopped working''

Dear all,

I just try to run the example in R brugs packages, but not only once. Loop is
added in this example. After several times (7, 11, or other random number),
there is an error message "r for windows gui front-end has stopped
working". This happened in two laptops with windows 7 and vista. I have
tried different versions of R (2.14.1 and 2.13) and Brugs packages (0.7.1 and
0.7-5). But it works well in a computer installed with Windows XP system.

Anyone has some idea how to avoid this crash in Windows Vista or 7 system?

Thanks,

Jim

I forgot to add the R codes. The following are the codes I used for this
problem:


###    Step by step example:    ###
library(BRugs) # loading BRugs

## Now setting the working directory to the examples' one:
setwd(options()$OpenBUGSExamples)

## add a simple loop
for (mn in 1:100){

## some usual steps (like clicking in WinBUGS):
modelCheck("Ratsmodel.txt")          # check model file
modelData("Ratsdata.txt")            # read data file
modelCompile(numChains=2)            # compile model with 2 chains
modelInits(rep("Ratsinits.txt", 2))  # read init data file
modelUpdate(1000)                    # burn in
samplesSet(c("alpha0", "alpha"))     # alpha0 and alpha
should be monitored
modelUpdate(1000)                    # 1000 more iterations ....

samplesStats("*")                    # the summarized results

## some plots
#samplesHistory("*", mfrow = c(4, 2)) # plot the chain,
#samplesDensity("alpha")              # plot the densities,
#samplesBgr("alpha[1:6]")             # plot the bgr statistics, and
#samplesAutoC("alpha[1:6]", 1)        # plot autocorrelations of 1st
chain

# force to print the current loop number
flush.console()
print(mn)
}
